Stop lights in the U.S. are green to 'go' but and a yellow to warn you it's going to go to red. In England the stop signs warn you when you are to go. So they are red, then yellow, then green. Is that not a little weird? Why do you need to be warned that the light is going to turn green.
If you drive into London, you get an automatic $14 pound traffic ticket. If you don't pay it within 24 or 48 hours, it doubles or triples. So a $14 pound ticket (which would be about $20 U.S.) could conceivably wind up being $40 or $80 if not paid efficiently.
They have these cool chip embedded credit cards in Europe now. When you pay for a purchase, the credit card goes into a special chip reading slot on the card reader where the owner of the card then puts in a pin number. No signature is required. This is so much safer than our system with signature required. No one can fake your signature and there would be much less credit card fraud. Why hasn't the U.S. adopted this very sensible system?
I know I thought of a couple more things but can't think of them right now. I'll get back with you later . . .
